摘　　要：文章采用磁力测量和侧扫声呐测量方法,对海南岛南部近海海底输气管道进行检测,并根据检测结果开展管道安全性评价。研究表明,研究区海底地形较平坦;检测范围完全覆盖预计区域;小部分管道呈现半裸露状态但未危及安全,管道整体状态良好。定期或不定期对海底输气管道进行检测,可保证管道安全,避免天然气泄漏造成海洋环境污染。In this paper,the inspection and test of offshore submarine gas pipelines in the south of Hainan Island were tried with the methods of magnetic survey and side-scan sonar,and pipeline safety evaluation was made on the basis of the testing results.The study showed that the submarine topography in the research area is rather flat;the testing completely covered the anticipated area;a small part of pipelines were half exposed but were still safe and in good conditions generally.Regular or irregular testing of the submarine gas pipelines could help to ensure safety of pipelines and avoid marine environmental pollution caused by natural gas leakage.
